Potentiates the properties of neuroleptics, narcotics, and in addition, hypnotic drugs, as well as ethanol.
Among the features of the hypnotic effect of Levan is the ability to prolong not only a segment of the slow wave sleep stage, but also a paradoxical one. The number of phases does not change. Thanks to this, the hypnotic effect of the drug acquires a noticeable physiological aspect.

Side effects of the levan Is

But it is necessary to take into account such side effects that arise with the use of sedative and hypnotic medicines: muscle relaxation together with hypersedition, and also weak disorders of psychomotor skills and cognitive activity, an increase in IOP values and signs of allergy.
In the morning, in the first few days of drug use, there may be a feeling of drowsiness, often disappearing after 2-3 days of therapy. The degree of severity, as well as the frequency of development of negative symptoms, depend on the size of the portion of the drug.
If a patient exhibits severe negative symptoms, it is necessary to reduce the size of the dosage or to cancel the use of the medicine.
